Technical Field

The invention belongs to the technical field of spinning, and particularly relates to a fabric finishing agent and a method for finishing a pure cotton fabric by using the same.

Background

With the continuous improvement of living standard, people have pursued higher pursuits such as health and comfort, not only to meet the simple requirements of clothes and eating residents. From the viewpoint of dressing, the good look and durability of the cloth are not pursued singly, but some special functionality of the clothes is desired. The summer is the sun exposure day and the season of people's profuse sweat, and people need to wear cool and comfortable clothes while protecting themselves from ultraviolet rays. This poses a challenge to our existing conventional textile fabrics, and fibrous fabrics with moisture-absorbing and cooling properties are therefore sought after by more and more people.

The existing moisture-conducting pure cotton fabric is easy to breed bacteria due to the sweat-absorbing characteristic, so that the health of a human body is threatened, and meanwhile, the existing preparation process of the pure cotton fabric is complex and has poor comfort in use, so that the existing preparation process needs to be improved.

Disclosure of Invention

Therefore, the invention aims to solve the technical problems of complex process, poor antibacterial ability and insufficient comfort of the existing moisture-permeable pure cotton fabric, and further provides a fabric finishing agent and a method for finishing the pure cotton fabric by using the same.

the invention provides a fabric finishing agent, which comprises a first finishing agent and a second finishing agent, wherein the first finishing agent comprises the following raw materials in parts by weight:

further, the second finishing agent comprises the following raw materials in parts by weight:

the invention also provides a method for finishing the pure cotton fabric, which uses the fabric finishing agent and comprises the following steps:

s1: soaking the pure cotton fabric in a first finishing agent for padding;

s2: spraying a second finishing agent on the surface of the padded pure cotton fabric;

s3: and (3) baking, soaping and drying the pure cotton fabric.

Further, in the padding method in the step S1, the second finishing agent is poured into a padding machine, the pure cotton fabric is padded and then placed into an oven, and the pure cotton fabric is dried at 60-80 ℃.

Preferably, the number of times of dipping and rolling in the padding is not less than 2 times.

Further, the spraying method in step S2 is to spray 2 layers, each layer having a thickness of 0.03-0.05 mm.

In the step S3, the baking temperature is 120-160 ℃, and the baking time is 2-6 min;

s3, the soaping temperature is 70-80 ℃, the time is 4-6min, wherein the soap solution for soaping is preferably prepared by using higher fatty acid to react with caustic soda, and then the effective part of the higher fatty acid sodium after the reaction is separated by salting out;

the drying in S3 is drying at low temperature of 40-50 deg.C for 2-3min, heating to 80-90 deg.C, and drying for 2-3 min.

The invention also provides a pure cotton fabric which is finished by adopting the pure cotton fabric finishing method.

The technical scheme of the invention has the following advantages:

(1) in the fabric finishing agent provided by the invention, in the first fabric finishing agent, the nano zinc oxide has obvious absorption and reflection effects on several wave bands of ultraviolet rays; the pentanediol is an organic solvent, generates a natural defense effect on water, and is matched with the organic siloxane, so that the waterproof performance is improved; the liquid crystal polyurethane belongs to a high-toughness substance, has good elasticity and flexibility, and cotton fabrics are treated by the liquid crystal polyurethane, namely, a layer of protective film is added on the cotton fabrics, and before the cotton fabrics are torn, the liquid crystal polyurethane material must be torn firstly, so that the tearing strength is greatly increased; the PNCS microgel belongs to micron-sized gel particles, is a polymer particle with an intramolecular cross-linking structure, can promote mutual cross-linking of all substances in the first finishing agent to promote fusion, and can also enhance the mechanical property, durability and waterproofness of the finished cotton fabric; quercetin-3-glucoside has antioxidant effect, and can prevent fabric and finishing agent components from being oxidized, and prolong the service life of clothes.

(2) In the fabric finishing agent provided by the invention, in the second fabric finishing agent, chitin and epsilon-polylysine have the functions of resisting and inhibiting bacteria and avoiding bacterial breeding; the nano silver ion is also a very high-efficiency broad-spectrum bactericide, and in a nano state, because the contact surface of the silver ion and the outside is greatly increased, the sterilizing capability of the nano silver ion is greatly improved, a very small amount of nano silver can generate a strong sterilizing effect, and 650 kinds of bacteria can be killed within a few minutes, so the nano silver ion can be widely applied to the existing textile and clothing industries, and simultaneously has a certain electromagnetic radiation prevention effect; the epsilon-polylysine has natural antiseptic effect, has wide antimicrobial spectrum, good stability, good bacteriostatic effect and wide antimicrobial spectrum compared with other antiseptic materials, and can inhibit the growth of microorganisms in cotton fabrics when being applied to the cotton fabrics.

(3) In the fabric finishing agent provided by the invention, the original structure of the chitin in the second finishing agent is partially grafted with the pentanediol in the first finishing agent, so that the solubility of the chitin is improved, and the chitin can form gel in a short time, has a good antibacterial and hemostatic function, and further seals wounds.

(4) In the finishing method provided by the invention, the padding of the first finishing agent on the pure cotton fabric enables the components of the first finishing agent to be coated on the fibers of the pure cotton fabric, and the spraying of the second finishing agent on the surface enables the pure cotton fabric to have a one-way moisture-conducting effect: because the inlayer is the cotton fabric, water, density are great after the moisture absorption, and the skin uses the spraying second finishing agent, and second finishing agent coating itself does not absorb the moisture, exposes in outer air, because the skin steam density is less inlayer steam density great, according to differential capillary effect and pressure difference principle, steam can follow the great meeting of concentration and remove to the place that the concentration is little, has caused the one-way wet function of leading of whole cotton fabric. According to the principle of one-way moisture conduction, water vapor on the surface layer can be quickly evaporated due to the density relation and the inertia effect, and a large amount of heat can be taken away by evaporation, so that the internal temperature is reduced. The body feels very cool, the body temperature is reduced, and the effect of rapid heat conduction is achieved. Therefore, the fabric has the properties of quick perspiration, dry heat conduction, moisture absorption and cooling.

(5) The finishing method is simple to operate, the obtained pure cotton fabric has the properties of quick perspiration, drying and heat conduction after being finished by the finishing method, clothes made of the cotton fabric have excellent moisture absorption and cool performance, can meet various different requirements of people, and has high practicability and wide application range, and meanwhile, the finished pure cotton fabric also has the ultraviolet resistance, the water resistance and the tearing strength, and also has the antibacterial and bacteriostatic properties, and the breeding of mold is avoided.
